Feasibility of Fiberglass Pretensioned Piles in a Marine Environment
The primary aim of the study was to investigate the feasibility of using fiberglass pretensioned piles to replace steel in a marine environment. As a consequence experimental investigations were carried out to determine the short term, long term and impact response of specimens pretensioned using S-2 glass/epoxy composites. For comparability, identical steel specimens were also tested. The study indicated that the response of identical fiberglass and steel pretensioned specimens is, in general, comparable and may be predicted with reasonable accuracy using non-linear finite element analyses incorporating appropriate material properties. However, the long term durability study indicated that the fiberglass strands suffered degradation under wet/dry cycles. Pre-cracked specimens deteriorated between 3-9 months of exposure and the uncracked specimens between 12-18 months. Scanning electron micrographs showed degradation of the glass fibers in the alkaline concrete environment. Recommendations for overcoming this problem are addressed in the report.
